So what? You don’t think a decent prepped W2 (lets say with the same porting time you put into your heads) wouldn’t be much quicker and faster?
If you don’t think that you are just shitting yourself. BTDT. I can tell you that you are cylinder head limited. Because you are bracket racing and going as fast as you want you are happy.
But claiming the push rod pinch doesn’t matter is nuts.
You can’t just change the area in the port and not have consequences.
